This invention relates generally to creel structures such as areprovided on spinning frames and the like to support the supply bobbinsfor the spinning operation, and more particularly to an improvedsupporting means allowing skewers to be used for carrying the supplybobbins, while obtaining the advantages of an overhead creel structurearranged to have the supply bobbins hung therefrom.

It has been long established prior practice to employ skewers forcarrying textile bobbins in a creel supply at a spinning frame or thelike; the skewers being spindlelike wooden members shaped for insertionthrough the bore of the supply bobbin core, with a shouldered baseportion thereof projecting below and a tip portion extending above thebobbin bore for insertion between vertically spaced creel platforms orthe like arranged to provide a fixed positioning support for the skewerbase portion and a fixed locating guide for the skewer tip.

More recently, bobbin hangers have been developed for overhead mountingtoo engage a bobbin bore at its upper end to allow hanging dispositionof the supply bobbins in a creel structure, and thereby facilitatesubstantially the placement of the supply bobbins in the creelstructure, as Well as providing increased flexibility through readyadjustment of the longitudinal spacing of the bobbin hangers fordifferent sizes of supply bobbins, as compared with the fixedvsupporting arrangement previously characteristic of creel structuresadapted for carrying the supply bobbins on skewers. However, such bobbinhangers have been found to raise objectionable difficulties inmaintaining the supply bobbins free enough for satisfactory withdrawalof the roving or other supply strand therefrom at a low enough tension,and the use of bobbin hangers has the further disadvantage of renderingob-olete the substantial supply of skewers that a textile mill normallyhas on hand in following the earlier established prior practice.

In accordance with the present invention, the advantages of an overheadcreel structure in ease of supply bobbin pacement and flexibility inaccommodating varying supply bobbin sizes are provided in an arrangementI that also allows skewers to be employed effectively for carrying thesupply bobbins, so as to allow continued use of these conventionalelements to obtain the much better low tension withdrawalcharacteristics thereof as compared with bobbin hangers. Brieflydescribed, these advantages are obtained according to the presentinvention by the provision of a bobbin skewer supporting meanscomprising a hanger bracket incorporating an upper end member formedwith a skewer positioning aperture, an aligned lower end member formedwith a skewer supporting recess, and an intermediate throat memberformed for clearing a bobbin carried by a skewer between these endmembers, with the upper end member of the hanger bracket additionallyincorporatin means for hanging attachment thereof in an overhead creelstructure.

These and other features of the present invention are described infurther detail below in connection with the accompanying drawings, inwhich:

FIG. 1 is a fragmentary elevation of an overhead creel structure fittedwith skewer supporting means embodying the present invention.

FIG. 2 is an enlarged side elevation detail of the skewer supportingmeans shown in FIG. 1;

FIG. 3 is a further enlarged top plan detail of the lower end portion ofthe skewer supporting means illustrated in FIG. 2;

FIG. 4 is a further elevation detail of the skewer supporting means asseen from the right in FIG. 2;

FIG. 5 is an enlarged bottom plan detail of the upper end memberemployed in forming the skewer supporting means illustrated in FIGS. 2and 4;

FIG. 6 is a top plan detail corresponding generally to FIG. 5; and

FIG. 7 is an enlarged fragmentary top plan detail of the upper endportion of the skewer supporting means illustrated in FIGS. 2 and 5.

Referring now in detail to the drawings, FIG. 1 illustrates generallythe arrangement of an overhead creel structure formed by vertical postmembers 10 fitted at their lower ends with mounting brackets 12 forspacing in an aligned series along the central longitudinal axis of aspinning frame or the like (not shown), and carrying at their upper endslateral arm members 14 on which longitudinal stringer members 16 aremounted to have supply packages P of roving bobbins or the like hungtherefrom.

The stringer members 16 are preferably of the type disclosed incopending application Serial No. 649,857, filed April 1, 1957, nowPatent No. 2,958,479, in which the bottom face is formed to provide anextending longitudinal slot at which fastening means, such as isindicated at 18, may be engaged for fixing a supply package P at aselected position lengthwise of a stringer member 16. The supportingmeans provided by the present invention is indicated generally by thereference numeral 20 and as illustrated in FIG. 1 as arranged on thestringer members 16 for supporting in depending relation therefrom thesupply packages P carried on skewers S extended through the bores of thepackage bobbins B.

As illustrated further in FIGS. 2 and 4, the skewer supporting means 20comprises, as previously mentioned, an upper end member at 22, a lowerend member at 24, and an intermediate throat member at 26. Theintermediate throat member 26, may suitably take the form of a rodelement shaped for clearing the supply package P to be supported, whilecarrying the upper and lower end members 22 and 24 in aligned relationat the opposite ends thereof.

The form of the lower end member 24 is further seen in FIG. 3 to includea rear shank portion 28 for securing attachment by welding or the likeat the adjacent end of the intermediate throat member 26, a recess at 30in which the lower end of a skewer S may be seated for supportinglocation thereat, and a substantially horizontal lip portion 32extending at the front thereof and defined by substantially verticalshoulders 34, angled in tangent relation from the back of the recess 36,so as to adapt the lip portion 32 as a lead-in guiding means fordirecting the lower end of a skewer S readily to a seated disposition inthe recess 30 as a supply package P is installed in place.

FIGS. 4 through 7 further illustrate the arrangement of the upper endmember 22 for positioning the upper extending end of a skewer S and foradditionally allowing hanging attachment of the skewer supporting means20 on the stringer member 16 of the creel structure. For these purposes,the upper end member 2-2 is, like the lower end member 24, formed with arear shank portion 36 for attachment, as by welding, at the adjacent endof the intermediate throat member 26, and is apertured at 38 to receivethe upper end of a skewer S freely for allowing initial over extensiontherethrough in seating the lower skewer end at the recess 30 in thelower end member 24, as well as subsequently allowing the upper skewerend to rotate freely therein. Also like the lower end member 24, thisupper end member 22 may be formed with a front lip portion 40 defined byshoulders 42 angled in tangent relation from the back of the aperture 38for iitially directing the upper skewer end readily thereto. Theaperture 38 is illustrated in the drawings as being formed with anextruded shape so as to present a sleevelike configuration to minimizewear at the upper skewer end. The aperture 38 might otherwise be fittedwith an insert of procelain or plastic or the like for the same purpose,and the recess 31 in the lower end member 24 might likewise be modifiedin a similar manner if desired.

Additionally, the upper end member 22 incorporates arm portions 44extending laterally to each side thereof with an upwardly angled shapetoward slotted extending ends at 46 to be engaged thereat by thepreviously mentioned fastening means 18 for hanging attachment on thestringer members 16, so as to utilize effectively the advantages of anoverhead creel structure while providing through the skewer supportingmeans 20 of the present invention the necessary bottom support foremploying skewers S to carry the supply packages P.

The present invention has been described in detail above for purposes ofillustration only and is not intended to be limited by this descriptionor otherwise except as defined in the appended claims.
